Abstract

Background: The main subject of the paper is development of three-dimensional numerical modelling method of children's hip joint. Anatomically correct as well as deformed due to cerebral palsy joints were taken into consideration. Materials and methods: The modelling process was carried out on data obtained from X-ray computer tomography. Specialized software was used to develop three-dimensional models of particular objects (e.g. pelvis, thigh bone) of hip joint. Results: The CT-data of two patients from Clinic of Children Orthopaedics and Rehabilitation of Lublin Medical University was used to perform three - dimensional geometrical models of hip joints. Finite element models were prepared also taking into account inhomogeneity of the bone tissue. Conclusions: RESULTS of our researches clearly show that three-dimensional, computer modelling of the children hip joint can be performed based on CT-data. Use of these methods will enable us to gain a better understanding of children hip joint deformation process and facilitate planning of therapy.
